To evaluate the application value of the QR code assisted technology for advanced interventional students during three-stage training.

From 2020 to 2021, 82 advanced interventional students from the First Affiliated Hospital of Zhengzhou University were selected as the research subjects, and all students were taught in three stages (for a period of 3 months). Experimental group (n = 41) used QR code assisted conventional explanation training, and control group (n = 41) used conventional explanation training. The differences between the two training modes were compared by theoretical examination, practical operation grading (excellent/good/general ) and questionnaire.

Both groups successfully completed the training tasks. The theoretical test score of the experimental group was (79.4 ± 7.4), while the control group was (71.5 ± 6.9), with a statistically significant difference (t = 3.50, P = 0.001). The excellent and good rate of practical grading in the observation group was higher than that in the control group [34 cases (82.9%) vs. 27 cases (65.9%)], with a statistically significant difference (χ² = 9.22, P = 0.03). The questionnaire showed that the observation group was superior to the control group in terms of learning efficiency (χ² = 18.30, P = 0.00), teaching methods (χ² = 6.61, P = 0.01), learning interest (χ² = 6.61, P = 0.01) and knowledge structure (χ² = 4.321, P = 0.03).

QR code assisted technology can improve the efficiency of three-stage training for advanced interventional students, which is worthy of further promotion.
